“Where talent can hit a target no one else can hit, a true genius hits a target no one else can see”. - Arthur Schopenhauer


Some people get bogged by tronics, while others have resistors and capacitors for dessert!  If you belong to this rare breed of circuit-mongers you are in for a treat!

Circuitrix is a platform for all electronics enthusiasts to exhibit their skills against the best of the best in this specialization. Circuitrix is an event which will test a participant’s knowledge on the basics of electronics.

In this event, participants will have to race against time to make the best possible circuit and prove their dominance.


The prelims portal will be open from 7 PM, 17th February 2017 to 11:59 PM, 19th February,2017. Please make sure that all the team members register for the event before starting the quiz(The team members' details will be asked during the quiz). The time duration of the quiz is 1 hour. One team can attempt the quiz only once. Click here to start the quiz.


Prelims 9 am to 12 pm -- March 3, 2017.

Finals  10 am to 5 pm --- March 4, 2017.

                 CASH PRIZE - INR 25000


OFF CAMPUS: Online test

  • This round is eliminative.

  • Online quiz will be held from 17th February, 7:00 pm to 11:59 pm 19th February.


Level-1: Objective round (multiple choice round)

Level 2:  Subjective round: A question will be released as soon as the objective round is completed, to which the participants have to submit their answer in the space provided on the site.

  • The top 40 teams from the online rounds will be selected for the on-site round.



Theory session:

  • Initially, the students will be taught exclusively few topics which are necessary to finish the final task. Then, there will be an assessment test at the end of the session, so that the students can improve to equip themselves for the final task.

  • This assessment is non-eliminative.

Final round:

  • This round involves the practical implementation of circuits for the problem statements which would be given on the spot.

  • The question will cover the concepts from the online tests and the theory class.


  • Duration: 3 hrs.

  • 40 teams divided into 2 batches of 20 with 2 different slots.    

  • Teams will be given some amount of virtual money.  

  • Components required for every problem statement will be on sale.

  • Depending on their problem statement, teams should decide their components and buy them with the provided virtual money.


Final round:

  • Working of the circuit.

  • How well it is practically implemented.

  • Time taken

  • Minimal money usage

  • The decision of the judges will be final.


  • Team should comprise of not more than 3 participants.

  • Prior registration is required in order to participate in the online round.

  • The decision of the judges is final.

Q1. How many participants per team?

Ans: Maximum of three.

Q2. Do all participants have to be from the same college?

Ans: No. The members of the team can be from different colleges.

Q3. Are there any prerequisites for participating in this event?

Ans: Just a basic knowledge on electronics will suffice for participating in the event.

For tutorials on basic electronics, digital and analog circuits, refer to the links given below:

Problem statement will be given on spot at the day of the event.


Sample questions

   Round 1:

        1) What does a full subtractor require for implementation?

        2) What type of feedback is used in sequential circuits?

        3)What type of components are used in SRAM and DRAM?

        4)What are Mealy and Moore mach?

    Round 2:

        1) Design a 4-bit serial in-parallel out shift register using D flip-flops. Assume a common clock is available. The output of shift register should be given as input to a combinational circuit that produces a logic high when inputs to it are 1001 or 1100 or 0010 and a logic low for all other inputs. Highlight all major connections and draw a legible diagram.

      2) Design a synchronous MOD-6 counter. Highlight all major connections and draw a legible diagram.

    Round 3:

    1) A number is to be displayed on a seven segment LED display. Its inputs are a, b, c, d, e, f and g. The first three inputs (i.e a, b, c) are to be obtained from task 1 and the next four inputs are to be obtained from task 2.


The inputs a, b, c are transferred serially (synchronously). The bit ‘c’ is transferred first followed by bits ‘b’ and ‘a’. The clock and data pulses transferred through the LED lights have to be received and taken as inputs. These need to be stored in a register and then be connected to the seven segment display appropriately.


Obtain the RPM of the motor in binary format. These will correspond to the last four bits (d, e, f, g) of seven segment display. The MSB is the ‘d’ bit and LSB is the ‘g’ bit. The binary format obtained will be of four bits at most.
